Tourist season in SB is a tough drive and parking is limited.  Smog wouldn't do in lovely Santa Barbara so they are encouraging people to use public transportation and they have made it easy with an extensive bus system and those wonderful electric shuttles. The beach has a walking trail, as well as one for biking and jogging not to mention rollerblades and skateboards, after all it is California. You can rent a pedal powered surrey for a fun time with the kids. Try this website for advise.
